Unable to load the 'nvidia-drm' kernel module on Ubuntu 18.04

Thanks for the quick response. I tried the following:
-sudo ./NVIDIA-Linux-x86_64-410.78.run --uninstall
-sudo add-apt-repository ppa:graphics-drivers/ppa
-sudo apt-get update
-sudo apt install nvidia-driver-418
-I rebooted the machine
-nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

So, no success yet. Everything was working fine until i started following instructions to install tensorflow 2.0 on Ubuntu 18.04(Cuda 10) from this page.

When I open up software updates, this is what shows up (attached snapshots)
